The LMH6647MF/NOPB is a single voltage feedback Operational Amplifier with rail-to-rail input and output. It offers high speed (55MHz), low voltage operation (2.7V) and shutdown capability option. Input common-mode voltage range exceeds either supply by 0.3V, enhancing ease of use in multitude of applications where previously only inferior devices could be used. Output voltage range extends to within 20mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650μA/amplifier, output current capability is kept at a respectable ±20mA for driving heavier loads. Important device parameters such as BW, slew rate and output current are kept relatively independent of the operating supply voltage by a combination of process enhancements and design architecture. In portable applications, the LMH6647 provides shutdown capability while keeping the turn-off current to less than 50μA.
